Answer:
t = 1862 s
Explanation:
To do this, we need first to determine the theorical detention time, which can be determined with the following expression:
t₀ = ∀/Q (1)
Where:
t₀: detention time
∀: Volume of the fluid in the reactor
Q: Flow rate in the reactor
With this time, we must use the following expression to determine the time that the workers will take to vent the tank:
C = C₀ e^(-t/t₀) (2)
From here, we must solve for time t, and the expression will be:
t = ln(C₀/C) * t₀ (3)
Now that we know the expression to use, let's solve for t. Using (1) to determine the detention time, ∀ is 1900 m³, and Q is 2.35 m³/s so:
t₀ = 1900 / 2.35 = 808.51 s
Now, let's solve for the time t. C will be 0.0015 mg/L (or 1.5 mg/m³ cause in 1 m³ we have 1000 L) and C₀ 15 mg/m³:
t = ln(15/1.5) * 808.51
t = 1861.66 s or simply 1862 sHope this helps

The molality of a solution is defined as the number of moles of a solute per kilogram of solvent. It depends on the mass of the solvent. It is denoted by m. It is also called Molal Concentration.
What is Molality?Molarity (M), which is determined by dividing the solute's mass in moles by the volume of the solution in litres, is the most widely used unit to express solution concentration: litres of solution/moles of solute equals M.
The following equation can be used to determine the molality: m = (Number of moles of the solute)/ (Mass of the solution in litres.) Molality is measured in kg/mol. The terms molality and molal concentration are interchangeable. The equation for calculating molality,
m = (Moles of the Solute, in Number)/ (Mass of the solution in litres.)
Molality is measured in kg/mol.Molality has an advantage over molarity in that it is unaffected by changes in temperature and pressure because it is determined based on mass rather than volume.

A dime weighs 2.5 g. What is the dollar value of 1 kg of dimes?
A dime weighs 2.5 g. $40 is the dollar value of 1 kg of dimes.
What is Dime?In American use, a dime is a 10-cent coin that is officially referred to as "one dime" and is worth one-tenth of a dollar. By virtue of the Coinage Act of 1792, the denomination was initially approved.
The dime, with dimensions of 0.705 inches (17.91 millimeters) in diameter and 0.053 inches (1.35 mm) in thickness, has the lowest diameter and is the thinnest of all U.S. coins now in circulation.
The term "dime" is derived from the Old French disme (modern French dîme), which means "tenth part" or "tithe" and is derived from the Latin decima [pars]. The only American currency now in widespread use that doesn't have a dollar or cent value is the dime. The cost of manufacturing a dime in 2011 was 5.65 cents. It costs ten cents to buy a dime. The value of a penny, often known as a one-cent coin, is one cent. A dime coin is equivalent to 10 one-cent coins in value (pennies).
Given that,
weights of Dime = 2.5 gm
Now, 2.5 g x 10 dimes = 25 gm
So, 1 kg = 1000 gm
Thus, 1000 / 25 = 4000 cents

Answer must be in M/s
The average rate of change of B from t=0 to t=362 s is [tex]0.001883 M/s.[/tex]
How to find the average rate of change?The average rate of change of B can be determined using the formula:
rate = (change in concentration of B) / (change in time)
We can calculate the change in concentration of B by subtracting the initial concentration of B from the final concentration of B:
change in concentration of B = final concentration of B - initial concentration of B
We can calculate the change in time by subtracting the initial time from the final time:
change in time = final time - initial time
We can use the stoichiometry of the reaction to convert the concentration of A to the concentration of B:
2A -> B
change in concentration of B = (2 * change in concentration of A)
We can use this information to calculate the average rate of change of B from t=0 to t=362 s:
change in concentration of B = [tex](2 * (0.425 M - 0.170 M)) = 0.680 M[/tex]
change in time = [tex]362 s - 0 s = 362 s[/tex]

You have 100 mL of a 6 M solution of NaCI and you need to dilute it to 400 mL. What is the molarity of the new solution?
Answer: 1.5 M
Explanation:
In order to find the molarity of the new solution, we need to use the formula M1V1 = M2V2, where M1 is the initial molarity, V1 is the initial volume, M2 is the final molarity, and V2 is the final volume.
Given that the initial volume is 100 mL and the initial molarity is 6 M, we can plug in the values and solve for M2:
6 M x 100 mL = M2 x 400 mL
M2 = (6 M x 100 mL) / 400 mL
M2 = 1.5 M
So the new solution will have a molarity of 1.5 M.
if pressure of a gas sample is quadrupled and the absolute temperature is doubled what factor does the volume of the sample change
To determine the volume factor change, we must make V2 the focus of the equation. Therefore, the volume factor change is (c) 1/2.
If the temperature rises four times, how will the pressure change?As the Kelvin temperature increases, the pressure increases. Direct proportionality governs the connection between the two sums.

The volume, in milliliters of 0.595 M iron (II) bromide that will contain 100 g of the substance will be 779.3 mL.
Molarity problemThe molarity of a solution is the ratio of the mole of solutes to the volume of the solution. Mathematically:
Molarity = mole/volume
Also, mole = mass/molar mass

100/215.65 = 0.4637 mol
Making the volume of the subject from the equation above:

Carbohydrates Maltose is sweet, but less sweet than glucose. Maltose is commonly used in brewing, baking and confectionery.
Trehalose:-
Trehalose is a disaccharide composed of two glucose units linked by an α,α-1,1-glycosidic bond. It is found in many organisms, including bacteria, fungi, plants, and some insects. Trehalose is sweet and is used as a sugar substitute. It is also used as a food additive, as well as in the production of some drugs and cosmetics.
In summary, Maltose and Trehalose are both disaccharides composed of glucose units, but they have different glycosidic bond linkage and different properties. Maltose is formed by the hydrolysis of starch and is less sweet than glucose, it is used in brewing, baking and confectionery. Trehalose is found in many organisms, it is used as a sugar substitute and a food additive, as well as in the production of some drugs and cosmetics.

Draw the organic product(s) of the reaction of acetophenone with H2NNH2, KOH.
If no reaction occurs, tell OWL by drawing ethane (CH3CH3).
Do not separate two structures with a + sign.
Answer:
From Wolff Kishner Reduction we can say that the product thus formed will be ethylbenzene.
Explanation:We know that acetophenone has (COCH3) attach to it as a functional group. When it reacts with hydrazine that is (NH2NH2) in the presence of a strong base such as KOH and heat, an intermediate known as hydrazone is formed. Hydrazone are a cousin of imines. Here the oxygen gets replaced with hydrazine and water is released. Then after deprotonation of NH we have protonation at carbon of the functional group. Then we again have deprotonation of NH and finally N2 is released and we have a protonation of carbon which results in ethylbenzene.
